However, extremely high Q values (see below) are often achieved not by using very long resonators, but rather by strongly reducing the losses per round trip. For example, very high Q values are achieved. In this paper, the concept of a micro ring resonator formed of waveguides in off-the-shelf polymers is presented. Extensive simulations were performed to determine appropriate dimensions for the waveguide and the design of ring and coupling zone as well as for the estimation of losses.
